AutoHome tent fabric specifications and ratings

Fabric evaluation criteria

A very good fabric cannot be just waterproof (it would be unsuitable as a camping fabric), one of the main properties of tent fabric must be breathability. Each square centimeter of fabric should contribute to the natural exchange of internal and external air. This characteristic promotes occupant comfort that is achieved by fast effective exchange of air and water vapor. Breathability is critical in environments with small volumes of air and prevents condensation, which can cause heat reduction in the tent. The natural flow-through of internal air containing moisture generated by the occupants of the tent allows a comfortable environment to be maintained.

To scientifically evaluate a fabrics qualities we consider the following:

The ratio between impermeability (maximum column of water the fabric is resistant to, according to ISO 811) and breathability (air permeability according to ISO 9237), calculated with reference to dimensions and inner volumes of the tents (habitable area) and area (in square meters) of the textile surface: basic criteria for a healthy environment.

Specific purpose of the fabric: for example the tents roof or side walls, including stresses and movement the fabrics are subject to as well as weather and climatic influences. Stretch (ISO 5081), and tear-resistance (ASTM D1424)

Color Stability (ISO 105B04) taking into consideration weather and climatic conditions, including the reaction of a combination of fabrics and threads.
